TYPEWRITING MACHINE.

T 0 all whom t may concern:

Bc it known that I, Jnssn A. B. SMITH, av citizen of the United States,residing in Stamford, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inTypewriting Machines, of which the following is a specification.

This invention relates to paper-carrying devices of front-strike-typewriting machines. Y

One of the objects of the invention is to facilitate the typing of shortwork or billsheets calling for entries upon only two or three lines, asin the case of gas bills. `Where but a few entries are to be made on abill-sheet, and a large number of sheets are to lbe typed, it is notsatisfactory toinsert the sheets from the rear and adjust them to typingposition, as these operations conf sume a great deal of time inproportion to the amount of actual ty ing. The present inventionsimplifies the introduction of the work-sheets and their adjustment tothe printin position.

For t lis purpose, in carrying outthe present invention, the work-sheetsare inserted at the front of the platen bottom end foremost. Their upperends are collated upon,

a table adjustably mounted on the machine in such position that, when awork-sheet is aligned at its to and side edges on ages carried by the tale, the work-sheet will be properly positioned at the printing point.pince the headings (the distance from the upper edge of a sheet to theiirst line to be typed) of various types of work-sheets may vary 1nlength, meaps are provided for adjusting the end gage of the Acollatingtable through a wide range longitudinally of the work-sheet. Thevariations in the lengths of work-sheets may require the adjustment ofthe end age through full line- .spaces, or through a raction of aline-space, or through several full line-spaces and a Vfraction of Valine-space. It is an object of this invention to provide for suchadjustment.

The work-sheets having been adjusted in position, means are providedwhereby' the sheets may be typed upon one, twogor three lines. For thispurpose,v the end gage of the collating table is mounted upon-a slid-`able plate adapted to'be moved upwardly and held in position atline-space intervals, v

the sheets, which are held to the table by sprlng-ngers, being moved uptothe end gage by hand. By the above-described means, a simple,rapiduand efficient method of typing short work-sheets is obtained.

Other features and advantages will here= inafter appear.

In the accompanying drawings, Figure 1 is a front view of a machine withthe invention applied thereto, onlyT the necessary co-operating parts ofthe machine being shown.

Figure 2 is a lvertical section taken` on the linel 2-2 of Figure 1. l

In the Underwood standard typewriting machine, a platen 10 is fixed uponan axle 11 journaledl in the end walls 12 of a shiftable platen-frameforming part of the usual typewriter carriage. Adapted to be mounted atthe front of the p aten is a front collating table 19 whose mounting comrises three portions, a central portion 20 an end 'portions 21 and 22.Tie-members 23 and 24 are provided to unite each end of the centralportion with the-adjacent end of an end porV tion. The ends of thecentral portion are fastened to the tie-members by sets of screws and26, lwhile the end portions are fastened to the tie-members by 'sets ofscrews 27 and '28. The end portions have upstanding members 30 and 31adapted to overlie longitudinally disposed bars 32 and 33 fixed to theplaten-frame by brackets 34 mounted upon tie-rods .35 and Walls of theplaten-frame and upward extensions 36. The outer edges 37 and 38 ofl theend portions are down-turned' and adapted lto` engage the outer edges ofbars 32 and 33. The bars 32 and 33 are Arovided with vopenings 40 and 41positione at 11nespace intervals apart and adapted to be engaged bystuds or screws 42 and 43 passing through the members 30 and 31. It isthus possible to slide the mountin for the table long said ars toward or19 longitudinally a number of away from thej platen for an 36 ixedlinVthe end.

full line-s aces within the llmits of the bars, andl t en secure themounting in adjusted position by means of said studs or screws 42 and43.

To allow for free sliding motion of the collating table upon the barswithout any binding action or too great lateral play, the j distancebetween studs 42 and 43 can be varied b means of screws 28 operating inlateral s ots 44 in end portion 22. Y

A. work-sheet may be inserted at the front of the platen bottom endforemost until the first line to be typed is at the printing point, theupper end of the sheet resting upon the collating table. The latterrmaybe moved toward or away from the platen until an upper end gage 45 comesin contact with the upper end of the work-sheet. The table is then fixedin position by screwing the studs 42 and 43 into the co-operatingopenings in bars 32 and 33. Thereafter, worksheets inserted at the frontof the machine to receive corresponding entries need only have theirupper ends positioned in contact with the upper end gage 45, and thesheets will be properly positioned to type the first line. Tt frequentlyhappens, however, that when a work-sheet is adjusted so that the firstline to be typed is at the printin point, the upper end gage 45 cannotbe rought into contact with the upper edge of the sheet, because thetable moves full linespaces forwardly or rearwardly while the sheetterminates at a fractional line-space position between two fullline-space positions of the table mounting on the bars 32 and 33.l Meansare, therefore, provided for moving the table toward or away from theplaten a fractional part of a line-space. Said means comprises the setsof screws 25 and 26 which operate in longitudinal slots 46 and 47.

When a new work-sheet is inserted bottom end foremost and adjusted sothat the first line to be typed is at the rinting point, the collatingtable is adjusted) along the bars 32 and 33 until the gage 45 contactswith the upper end of the sheet. Tf the sheet terminates between twofull line-space -positions of the table on the bars, the table is fixedon said bars at the nearest full linespace position, and the fractionaladjustment is accomplished by the screws 25 and 26 operating in theslots 46 and 47. The table is then in position to facilitate theadjustment of any number ofzsuccessive sheets of the same size. To aidin positioning the sheets rapidly, an edge gage is provided on one side.Tn this case, an edge gage 50 is mounted at the left side, and comprisesa gage-member 51 and a fiat member 52 mounted and slidably adjustable onthe end portion 21 by means of screws 53 operating in lateral slots 54.

ere more than one line is to be typed,

' means must be provided for suitably gaging Ysaid work-sheets atline-space intervals.

the end e central This is accomplished by mountin gage 45 on a slidablelate 6.0.

portion 20 of the col ating table comprises 62 is xed to the rear a rearbar 61 and a top plate 62. The plate ar 61 by screws 63 maaiercountersunk in the top late, the countersunk portions of the p ate 62providing clearance between the top plate and the rear bar for theslidable plate' 60. The latter has cut-out portions 64 adapted to clearthe screws 63 Awhen it is moved upwardly. For moving the slidable plateupwardly, a fingerpiece 65 fixed thereto is moved toward the left. Pins66 fixed to the top plate 62 project into cam-slots 67 provided withdwells 68 atvtheir ends. When finger-piece 65 is moved to the left,plate 60 rides upwardly on pins 66. A sprmg 70, fixed to the rear bar,is provided with a pin 71 adapted to project through an opening in therear bar and press against the slidable plate. Three openings 7 2, 73and 74 are provided in the plate 60 corresponding to the lowest and tworaised positions of the plate, each raised position being one line-spaceabove the previous position. The pin 71, lodging in the openings 72, 73and 74, will hold the plate in each position, and, in addition, the pins66, riding on dwells 68, will hold the plate 60 firmly in lowest andhighest ositions. Where more than three lines are to e typed, longercam-slots 67 and more openings similar to 72, 73 and 74 may be provided.Spring lingers 75, attached to the near plate and bent over to contactwith the front plate, aid in holding the work-sheets in position. Theloop of the spring is suiciently large not to interfere with the upwardmovement of the slidable plate.

Variations may be resorted to within the scope of' the invention, andportions-of the improvements'may be used without others.
